There is no 100% guarantee about a correct order with z-sorting. If your object is convex or has similar sizes for faces it is OK, otherwise there are surprises, whatever the criterion for z is... You can have a case where A visually overlaps B; B, C; C, A; so z-sorting always fails. You have to design you objects carefully... My own engine does (still...) use z-sorting, so I have suffered a bit with these problems... See http://members.xoom.com/gdemont/e3d.htm HTH -- Gautier
